Embodiment Construction

[0040] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0041] Such as figure 1As shown, the present invention provides a face beauty prediction method based on multi-task learning, and the present invention enhances the accuracy of face beauty prediction by adding expression recognition and age recognition. During the construction of the multi-task face database, the constructed database image contains three labels: facial expression attribute, age attribute and face beauty attribute, for subsequent multi-task training and prediction; in the multi-task training process, each task Share the network parameters and learn the shared features, so as to improve the accuracy of the network for single-task learning. By using a deep learning network for multi-task learning, the shared representation layer can enable common tasks to better combine relevant information, and the task-specific layer can model tas...

Abstract

The invention provides a human face beauty prediction method based on multi-task learning. The method comprises the steps of constructing a multi-task human face database and constructing a multi-taskhuman face beauty prediction model. According to the invention, the accuracy of face beauty prediction is enhanced by adding expression recognition and age recognition. In the multi-task face database construction process, the constructed database image comprises three labels including a face expression attribute, an age attribute and a face beauty degree attribute, so that subsequent multi-tasktraining and prediction are facilitated. Network parameters are shared among tasks in a multi-task training process. Shared features are learned, so that the accuracy of learning a single task by a network is improved. The multi-task learning is carried out by using a deep learning network. A shared representation layer can enable tasks with generality to be better combined with correlation information. A task specific layer can independently model task specific information. Network parameters can be optimized by using samples from different tasks. Meanwhile, the multi-task performance is improved.

Description

technical field [0001] The invention relates to the technical field of human face beauty evaluation using image processing and machine learning technology, in particular to a multi-task learning-based human face beauty prediction method. Background technique [0002] It is human nature to love beauty, and everyone has the heart to love beauty. Aristotle said: "A beautiful face is a better testimonial". The favorable impression of beauty exists in daily life and has a great influence on people's daily life. Research on the beauty of human face is a frontier topic in the research on the nature and laws of human cognition that has emerged in recent years. Exploring how to better measure beauty will help to obtain scientific, objective and quantifiable human face beauty codes, an eternal theme of human beings. The description of human face beauty has made great progress in the interdisciplinary field of human face beauty research. [0003] In real life, people have different ...
